Quick-Change Spargers

In bioreactor systems, optimal mass transfer of gases like oxygen or carbon dioxide is difficult to accomplish. Oxygen, in particular, is poorly soluble in water - and even less in cell culture and fermentation broths. Oxygen transfer is aided by agitation used to mix nutrients and to keep the cell culture or fermentation homogeneous. There are limits to agitation speed due to high power consumption as well as damage to organisms resulting from excessive tip speed. Agitation alone does not provide adequate mass transfer. Using a Mott porous metal sparger greatly increases mass transfer rates in this equipment. The introduction of gases into stirred or unstirred reactor vessels via millions of tiny bubbles increases the gas-to-liquid contact areas allowing for optimal mass transfer rates.

We make products from extremely small drug implants and building size filtration systems. Custom designing our products to fit into your product or process is what we do. See a starting list of porous metal product geometry. Our customers often require a integration into hardware and housings - we do that, too. Forming, machining, brazing, and welding are just some of the capabilities we use to customize dimensions or integrate our product to hardware connections.

Our customers may choose from an extensive list of material options to meet the specifications of their product application. We even source new materials through our supply chain for some of the most extreme technology advancements. Below are just some of the options available:

A virtually infinite combination of hardware connections are available for design. We are capable of sourcing and assembling the connection you desire using years of experience and special equipment. For example, welding porous metal products is significantly different than solid to solid. If done improperly, blowouts can occur or leak paths can form if done improperly, causing waste and poor performance. Additionally, when assembling porous metal media into products, surface damage can occur which will dramatically impact the products performance. We're experienced in all types of welding an assembly, use our manufacturing capability to your advantage.

Mission critical applications often require a host of unique properties and desired levels of cleanliness. Take advantage of our organic free processes and our Class 100 (ISO 5) and Class 10,000 (ISO 7) clean room manufacturing capabilities if your product and industry demands top cleanliness. In addition, post-treatments can be used to achieve additional performance characteristics, such as hydrophobic properties or additional strength. Some of these capabilities include:

High regulated and specialized industries require significant quality reviews, process documentation, and inspection and test plans. Experienced with medical, pharmaceutical, automotive, aerospace, nuclear, and other industries, we are ready to handle complex quality reporting requirements. Our customers often have specific agency approvals and tests and request specific sampling plans - send them our way. Here are a few examples of what we handle:

In addition, our engineering teams have years of experience with the latest design specifications of industries like semiconductor, medical, and aerospace. Save time and effort by using their knowledge of filtration and flow control applications by having them design with you.

Packaging and shipping needs should be considered with the design process as many options are available. For example, certain industries require very specific bagging requirements to minimize particle contribution and utilize nylon or barefoot bags vice polymer.

Getting the parts when you want them is important to us. We offer shipping and inventory solution services, including:
- Expedited Shipments
- KanBan Inventories
- Portal Management
